I wrote the the Dexter's 'Ask the Expert' folks and got a reply as lisred below. I haven't read into all of it, but here's the response:

You will want to request LIT-001-00 and possibly include the Running
Gear Catalog LIT-122-00, and the Kit Catalog LIT-119-00 to help in
identifying and ordering parts. Your MHU axle is very similar to our
axle model D60 with 12 x 2" electric brakes.
Replacement seal kit is K71-305-00
Replacement outer bearing kit is K71-307-00
Replacement inner bearing kit is K71-390-00
Replacement complete brake assembly is K71-536-00 for your left hand
brake.
Replacement complete brake assembly is K71-537-00 for your right hand
brake.
or Replacement shoe & lining kit K71-048-00.
Replacement magnet kit K71-105-00.
You are correct that your axle is NOT the "one time use" axle that
everyone thinks it is. The axles with the bolt on brake are the utility
version which was very similar to the true mobile home axle with the
weld on brake.
